Grim Sleeper No. 139

Grim Sleeper No. 139 has a bit of interesting signage that says “The Mail Slot” and gives a phone number that appears to be 419-0395. I’m not able to locate this number or business, so I’m assuming it’s defunct. Does the “82” indicate 1982? A car in the background looks like a Volkswagen Beetle but otherwise identifying the cars will take more research. ALSO Grim Sleeper Nos. 4 and 52 Grim Sleeper Nos. 48-49 Grim Sleeper Nos. 51-53.
